TECHNICAL FIELD

The present disclosure relates to a fastening assembly, a holding mechanism, as well as a bracket and a remote controller using the holding mechanism.

BACKGROUND

With the development of science and technology, aerial photography has emerged and become increasingly popular, and aerial photography with unmanned aerial vehicles is increasingly favoured by photographers because of lower costs and safety thereof in comparison with manned aerial photography. Aerial photography with unmanned aerial vehicles is usually carried out by using an aerial vehicle which carries a shooting device, such as a video camera or a photo camera, for shooting. Generally, a photographer uses a remote controller to control the flight of the aerial vehicle, and in order to watch the shooting effect in time, a displaying device such as a display and a mobile phone needs to be mounted on the remote controller, wherein the displaying device is fixed on the remote controller via a holding device. The holding device usually comprises a first and a second clamping member for clamping the displaying device and the first and second clamping members are elastically connected and movable relative to each other, such that the holding device is applicable to displaying devices such as mobile phones of different sizes.

However, the holding device is not applicable to all displaying devices in a larger size range, such as a mobile phone and a tablet, etc., and therefore the application range thereof is largely limited. Moreover, the holding device elastically clamps the displaying device via the first and second clamping members, and therefore the clamping force is small and the clamping is unreliable; and when the holding device shakes, the displaying device can easily fall off of the holding device.

The operating member 165 is in an approximately cylindrical shape and can be movably sheathed on the fastening member 163 for providing a convenient operating part for a user, such that the user can screw the fastening member 163 out of the locking member 161 via the operating member 165. A first sheathing hole 1651 and a second sheathing hole 1653 are provided on the operating member 165 along the axial direction thereof, and the first sheathing hole 1651 and the second sheathing hole 1653 are in communication with each other and penetrate the entire operating member 165. The first sheathing hole 1651 is provided close to the locking member 161 and the second sheathing hole 1653 is provided on the end of the first sheathing hole 1651 which is far away from the locking member 161. The bore diameter of the second sheathing hole 1653 is larger than that of the first sheathing hole 1651, such that a stepped surface 1655 is formed at the position where the first sheathing hole 1651 and the second sheathing hole 1653 are connected. The stepped surface 1655 is used to abut against the flange part 1639 to prevent the operating member 165 from falling off of the fastening member 163 when the operating member 165 moves along the fastening member 163. A snap-fitting part 1657 protrudes from and is formed on the inner wall of the first sheathing hole 1651. In this embodiment, the number of the snap-fitting parts 1657 is two, and each snap-fitting part 1657 corresponds to one snapping part 1637. The distance between the two snap-fitting parts 1657 is smaller than the maximum outer diameter of the mating part 1635 and the abutting and bearing part 1633, and when driven by an external force applied along the axial direction of the operating member 165, the snap-fitting parts 1657 can slide along the lengthwise direction of the sliding groove 1638 and are accommodated in the corresponding snapping part 1637. When the operating member 165 is driven by an external force to rotate relative to the fastening member 163, the snap-fitting part 1657 slides in the snapping part 1637 along a circumferential direction and abuts against the side wall of the snapping part 1637. The operating member 165 continues rotating when driven by the external force, the snap-fitting part 1657 pushes against the side wall of the snapping part 1637 to drive the fastening member 163 to rotate along with the operating member 165, such that the fastening member 163 moves relatively further away from or closer to the locking member 161.

The resetting member 167 is sheathed on the mating part 1635 and is accommodated in the second sheathing hole 1653. In this embodiment, the resetting member 167 is a helical compression spring. One end of the resetting member 167 abuts against the flange part 1639 and the other end abuts against the stepped surface 1655. When the operating member 165 is relatively far away from the flange part 1639, the snap-fitting part 1657 abuts against the end surface of the abutting and bearing part 1633 and the resetting member 167 is in a normal state. When the operating member 165 is driven by an external force to move close to the flange part 1639, the snap-fitting part 1657 slides along the sliding groove 1638 towards the corresponding snapping part 1637 and the resetting member 167 is gradually compressed. When the snap-fitting part 1657 slides to the snapping part 1637 and is steadily accommodated in the snapping part 1637, the resetting member 167 is in a compressed state and stores elastic energy. At this time, abutted by the resetting member 167, the end surface of the snap-fitting part 1657 abuts against the side wall of the snapping part 1637. When the operating member 165 rotates under the driving by an external force to cause the snap-fitting part 1657 to slide along the circumferential direction of the fastening member 163 on the side wall of the snapping part 1637 to the corresponding slide groove 1638, the end surface of the snap-fitting part 1657 is no longer stopped by the side wall of the snapping part 1637, and, under the action of a resetting elastic force of the resetting member 167, the snap-fitting part 1657 slides along the sliding groove 1638 and moves away from the flange part 1639, such that the operating member 165 as a whole moves away from the flange part 1639.

The two side walls 3235, the top housing 3231 and the bottom housing together form an accommodating cavity 3237 and the accommodating cavity 3237 is used to partially accommodate the second clamping member 34. A mounting hole 3239 is located on and penetrates one of the two side walls 3235. The mounting hole 3239 is located at the end of the corresponding side wall 3235 which is far away from the first clamping part 3233 and is used to mount a part of the structure of the limiting assembly 38.

The first protecting member 325 covers the top housing 3231 and the surface of the first clamping part 3233 facing away from the remote controller body 201, and is used to protect the clamped displaying device from scratches. In this embodiment, the first protecting member 325 is made of an elastic material. In particular, the first protecting member 325 may be made of foam. It is understood that the first protecting member 325 can also be made of another elastic material, such as rubber.

The second clamping member 34 is partially and movably inserted in the accommodating cavity 3237, and comprises a moving part 341, a second clamping part 343 provided on one end of the moving part 341, and a second protecting member 345 provided on the second clamping part 343.

Please refer to FIGS. 7 and 9, the moving part 341 is an approximately rectangular plate and is accommodated in the accommodating cavity 3237. A limiting part 3411 is formed on the side of the moving part 341 facing towards the mounting hole 3239. In this embodiment, the limiting part 3411 is in a sawtooth rack shape and is used to snap with the limiting assembly 38 so as to limit the mounting position of the second clamping member 34 relative to the first clamping member 32. The moving part 341 is also provided with a meshing part 3413 on the side facing towards the bottom housing 3211, and the meshing part 3413 is formed corresponding to the meshing member 3219. In this embodiment, the meshing part 3413 is a rack meshing with the meshing member 3219. When the moving part 341 slides relative to the first clamping member 32, the meshing part 3413 meshes with the meshing member 3219, such that the sliding is smoother and resistant to shaking.

The second clamping part 343 is provided on the end of the moving part 341 which is far away from the first clamping part 3233 and faces the second clamping part 343 in a parallel manner. The second clamping part 343, the first clamping part 3233 and the top housing 3231 together form a clamping space (not marked in the figures) for accommodating the displaying device. Under the action of an external force, the second clamping part 343 can move relatively away from or close to the first clamping part 3233, such that the holding mechanism 30 can hold displaying devices of different sizes.

The second protecting member 345 is provided on the side of the second clamping part 343 facing towards the first clamping part 3233, and the material and function thereof are approximately the same as the first protecting member 325. In order to avoid redundancy, details will not be repeated herein in the description.

The first elastic member 36 is provided between the moving part 341 and the top housing 3231, one end thereof is connected to the bent part 3213 and the other end is connected to the second clamping member 34. In this embodiment, the first elastic member 36 is a compression spring. In an original state, i.e. when the moving part 341 is almost completely accommodated in the accommodating cavity 3237, the first elastic member 36 is in a compressed state. When the second clamping part 343 of the second clamping member 34 moves towards the direction away from the first clamping part 3233, the first elastic member 36 is gradually stretched to store elastic energy, so as to provide a restoring force of movement to the second clamping member 34.

Furthermore, the first clamping member 32 further comprises a third clamping part 327, and the third clamping part 327 is rotatably connected to the first housing 321 or/and the second housing 323. When the third clamping part 327 rotates to the position perpendicular to the first housing 321 and/or the second housing 323, a clamping space for clamping external devices such as a tablet computer or a mobile phone is formed between the third clamping part 327 and the second clamping part 343.

In particular, in the embodiments as shown in the figures, the third clamping part 327 is rotatably connected to the second housing 323 via a pivot shaft, and an accommodating groove for accommodating the third clamping part 327 is provided on the second housing 323. When the third clamping part 327 rotates to the position perpendicular to the first housing 321 and/or the second housing 323, the third clamping part 327 abuts against the side wall of the accommodating groove facing the second clamping part 343.

The specific structures of the third clamping part 327 can be designed according to different requirements, for example, in the embodiments as shown in the figures, the third clamping part 327 is a clamping hook and can be snapped with an external device such as a tablet computer or a mobile phone to prevent the external device from falling off.

Please refer to FIG. 10, the limiting assembly 38 is provided on the bottom housing 3211 corresponding to the mounting hole 3239 and is used to be snapped with the limiting part 3411, so as to limit the mounting position of the second clamping member 34 relative to the first clamping member 32. The limiting assembly 38 comprises a pivot shaft 381, a limiter 383 rotatably sheathed on the pivot shaft 381, and a pressing member 385 and the second elastic member 387 both provided on the limiter 383.

The pivot shaft 381 is fixedly provided on the top housing 3231 and close to the limiting part 3411 on the moving part 341. The limiter 383 is in an approximately bent block shape and the approximately middle position thereof is rotatably sheathed on the pivot shaft 381. Under the action of an external force, the limiter 383 can rotate around the pivot shaft 381. In this embodiment, the limiter 383 is a rotating stir wheel with one end thereof being snapped with the sawtooth rack of the limiting part 3411 and the other end thereof being an operating end. Particularly, the limiter 383 comprises a rotating part 3831 and a pressing part 3833 formed on one end of the rotating part 3831. The rotating part 3831 extends from the pivot shaft 381 towards the limiting part 3411; the pressing part 3833 extends from the pivot shaft 381 towards the mounting hole 3239; and a certain angle is formed between the rotating part 3831 and the pressing part 3833. The end of the rotating part 3831 which is close to the limiting part 3411 protrudes to form a stopping part 3835. In this embodiment, the stopping part 3835 is in a protruding tooth shape and is used to snap the saw teeth of the limiting part 3411. The pressing member 385 is mounted in the mounting hole 3239 with one end being abutted against the pressing part 3833 of the limiter 383 and the other end protruding out of the side wall 3235. One end of the second elastic member 387 is connected to the pressing part 3833 and the other end is connected to the top housing 3231. In this embodiment, the second elastic member 387 is a helical compression spring.

When the pressing member 385 is pressed by an external force, the limiter 383 is driven thereby to rotate around the pivot shaft 381, such that the second elastic member 387 elastically deforms and is compressed, and at the same time, the pressing part 3833 brings the stopping part 3835 to move away from the limiting part 3411, therefore the stopping part 3835 is no longer snap-fitted with the limiting part 3411, and the second clamping member 34 can move relative to the first clamping member 32. When the external force is lifted and under the action of the elastic restoring force of the second elastic member 387, the limiter 383 rotates reversely around the pivot shaft 381 and the stopping part 3835 is again snapped in the limiting part 3411, such that the second clamping member 34 is fixed relative to the first clamping member 32.

When assembling the bracket 100 in this embodiment, firstly, the limiting assembly 38 is arranged on the second housing 323 and the moving part 341 is arranged in a parallel manner on the top housing 3231, such that the stopping part 3835 is snapped in the limiting part 3411. The meshing member 3219 is rotatably arranged on the bottom housing 3211; the first elastic member 36 is connected between the bent part 3213 and the second clamping member 34; and then the first housing 321 is snap-fitted on the second housing 323, such that the meshing member 3219 is meshed with the meshing part 3413. Next, the first protecting member 325 and the second protecting member 345 are arranged on the first clamping part 3233, the top housing 3231 and the second clamping part 343. Then, the holding mechanism 30 is mounted on the connecting frame 12 via the fastening assembly 16, and then the locating assembly 14 is arranged on the connecting frame 12. When the bracket 100 needs to be mounted on the remote controller body 201, firstly, the fastening shaft 141 is inserted in the locating hole of the remote controller body 201 and then the fastening sleeve 143 is screwed in the locating hole, thereby firmly mounting the bracket 100 on the remote controller body 201.

Please again refer to FIG. 1, wherein in a non-use state, the holding mechanism 30 is approximately parallel to the remote controller body 201, the top housing 3231 thereof faces the remote controller body 201, and the first clamping part 3233 is partially accommodated in the accommodating space 127 of the connecting frame 12. At this time, the fastening assembly 16 steadily fixes the holding mechanism 30 on the connecting frame 12 and the operating member 165 of the fastening assembly 16 is relatively close to the locking member 161.

When using the bracket 100 and the remote controller 200 of the present disclosure, firstly, the operating member 165 rotates to cause the snap-fitting part 1657 to correspond to the sliding groove 1638 and then the operating member 165 is pulled to move away from the locking member 161. When the snap-fitting part 1657 slides into the snapping part 1637 along the sliding groove 1638, the operating member 165 is slightly rotated along a first direction to enable the snap-fitting part 1657 to be dislocated from the sliding groove 1638 and to abut against the side wall of the snapping part 1637. The operating member 165 continues rotating along the first direction, the operating member 165 pushes against the side wall of the snapping part 1637 via the snap-fitting part 1657, such that the fastening member 163 as a whole rotates and moves relatively away from the locking member 161, thereby enabling the two locking parts 3215 to be restored elastically and the connecting part 125 clamped between the two locking parts 3215 to be released. At this time, the holding mechanism 30 is rotatable relative to the seat 10.

Secondly, the holding mechanism 30 rotates around the fastening assembly 16 until the holding mechanism 30 rotates to a required operating angle, the operating member 165 rotates along a second direction opposite to the first direction, such that the operating member 165 brings the fastening member 163 to rotate until it is screwed with the locking member 161, and the fastening member 163 and the locking member 161 together clamp the two locking parts 3215, thereby fixing the holding mechanism 30 relative to the seat 10. Again, the operating member 165 slightly rotates along the first direction, and the operating member 165 is released after the snap-fitting member 1657 corresponds to the sliding groove 1638. Under the action of the elastic restoring force of the resetting member 167, the snap-fitting part 1657 slides along and moves away from the flange part 1639 along the sliding groove 1638, and the operating member 165 as a whole is relatively close to the locking member 161.

Then, an external force is applied to the pressing member 385, such that the snap-fitting between the stopping part 3835 and the limiting part 3411 is lifted, and at the same time, the second clamping part 343 is pulled to enable it to move away from the first clamping part 3233. At this time, the first elastic member 36 is stretched and stores elastic energy. When the spacing between the first clamping part 3233 and the second clamping part 343 meets requirements, the second clamping part 343 and the pressing member 385 are released, such that the first clamping part 3233 is fixed relative to the second clamping part 343.

At last, a displaying device such as a mobile phone, a display or a tablet computer is mounted between the first clamping part 3233 and the second clamping part 343. The pressing member 385 is pressed again, and under the action of the elastic restoring force of the first elastic member 36, the second clamping member 343 is relatively close to the first clamping part 3233 and abuts against the displaying device. The first elastic member 36 still has the tendency to recover from a deformed state to a normal state and the elastic force thereof is converted into the clamping force for the displaying device, thereby holding the displaying device on the holding mechanism 30. The pressing member 385 is released again to enable the stopping part 3835 to once again be snapped with the limiting part 3411, and the clamping part 3233 and the second clamping part 343 are thus further fixed so that the displaying device is firmly clamped on the holding mechanism 30.

When the installation angle of the holding mechanism 30 relative to the remote controller body 201 needs to be adjusted, the fastening assembly 16 is released according to the method, such that the holding mechanism 30 is rotatable relative to the seat 10. The holding mechanism 30 rotates to the needed installation angle, and the holding mechanism 30 is once again fixed relative to the seat 10 via the holding mechanism 16. Such holding mechanism 30 of the remote controller 200 of the present disclosure uses both the first clamping part 3233 and second clamping part 343 to clamp the displaying device, the second clamping part 343 can move relative to the first clamping part 3233, such that the bracket 100 can be applied to displaying devices of different sizes and the application range of the holding mechanism is broad. In addition, the holding mechanism 30 limits the distance between the first clamping part 3233 and the second clamping part 343 by snapping with the limiter 383 and the limiting part 3411, such that the holding mechanism 30 is applicable to displaying devices with larger size differences, which further enlarges the application range of the holding mechanism. The limiter 38 and the limiting part 3411 can be firmly snap-fitted, such that the clamping from the holding mechanism on the displaying device is more reliable. Moreover, the installation position of the holding mechanism 30, as a whole, relative to the remote controller body 201 can be adjusted via the fastening assembly 16, such that the use of the remote controller 200 is more flexible.

It is understood that the resetting member 167 can be omitted and when using the bracket 100, the operating member 165 can be reset manually.

It is understood that the first elastic member 36 can be an elastic member of another structure, for example, a torsional spring, a coil spring, an elastic plate, an elastic sleeve, etc., and one end of the first elastic member 36 is connected to the first clamping member 32 and the other end is connected to the second clamping member 34, thereby providing a restoring force of movement for the second clamping member 34 or providing a clamping force for the second clamping member 34 in an operation state, such that the holding mechanism 30 can hold displaying devices of different sizes. It is understood that the number of the first elastic member 36 can be one or more.

It is understood that the first elastic member 36 can be omitted, and when using the holding mechanism 30, the mounting position of the first clamping member 32 relative to the second clamping member 34 can be limited by snapping the limiting assembly 38 of the first clamping member 32 onto the second clamping member 34, or separating the two from each other, thereby adjusting the distance between the first clamping part 3233 and the second clamping part 343, and the holding mechanism 30 can be applied to displaying device of different sizes.

It is understood that the second elastic member 387 can be an elastic member of another structure, for example, a torsional spring, a coil spring, an elastic plate, an elastic sleeve, etc., and one end of the second elastic member 387 abuts against the first clamping member 32 and the other end abuts against the pressing member 385 to provide a restoring force of movement to the limiter 383.

It is understood that the second elastic member 387 can be omitted and the limiter 383 may be designed with an elastic structure, and when an external force is applied, the limiter can be snapped with or separated from the limiting part 3411. Alternatively, the limiter 383 as a whole is arranged on the second housing 323 and can be a pluggable structure, and the stopping part 3835 on the limiter 383 is snapped with or separated from the limiting part 3411 by inserting the limiter 383 into the second housing 323, or pulling the limiter out from the second housing 323.

It is understood that the fastening assembly 16 can be omitted, and when assembling the bracket 100, the holding mechanism 30 may be fastened on the seat 10 via a screw.

It is understood that the number of snap-fitting parts 1657 can be one or more, and accordingly, the numbers of the snapping part 1637 and the sliding groove 1638 can also be one or more. When the numbers of the snap-fitting part 1657, the snapping part 1637 and the sliding groove 1638 are more than one, the plurality of snap-fitting parts 1657 are formed on the inner wall of the first sheathing hole 1651 separate from each other with a spacing in between, and the plurality of snapping parts 1637 are formed on the mating part 1635 separate from each other and is in a one-to-one correspondence relationship with the plurality of snap-fitting parts 1657.
